She is stationary  between  3 PM and 3:30 PM  = 1/2 hr

She is also stationary between 4 PM and 5 PM  = 1 hr

She is also  stationary between 6:30 PM  and 7:30 PM  = 1 hr

 

Total time  for  the journey  =   6 hrs  [ 8 PM  -  2PM]

 

So  she is stationary  for  [ 1/2 + 1 + 1/2 ]  =  2 hrs

 

And she travels   [ 6 hrs  -  2 hrs  ]  =  4 hrs

 

 

cool cool cool
